I looked up a few videos where i can understand maybe a quarter of it's lessons.
The thing is that, if i want to self host a vpn server, i can't do it, when i'm behind cgnat.
So i stumbled on ipv6 and that it is mabe possible with that. But i understand so little that i'm not sure.
So is it possible to make a VPN connection from a phone to a vpn-server-device like a router with a sim card, which is behind cgnat?
What i understand out of mentioned videos, is that if all devices use ipv6 only than it can work.
The video is called:
"Ipv6 why end to end connectivity matters and how it benefits you"
